Consider:
---
struct Foo {
  ~this() {}
}

@safe {
  class Bar {
    Foo f;
  }
}
---

DMD 2.057 Git (887dda0ba) fails with:
---
Error: safe function '~this' cannot call system function '~this'
---

I didn't think about what the best solution for this yet (what exactly is a
»safe class« in the first place?), but the error message should certainly be
improved.
